Universal scaling of finite-temperature quantum adiabaticity in driven many-body systems
Li-Ying Chou, Jyong-Hao Chen
Establishing quantitative adiabaticity criteria at finite temperature remains substantially less developed than in the pure-state setting, even though realistic quantum systems are…
Quantum adiabaticity in many-body systems and almost-orthogonality in complementary subspace
Jyong-Hao Chen, Vadim Cheianov
We investigate why, in quantum many-body systems, the adiabatic fidelity and the overlap between the initial state and instantaneous ground states often yield nearly identical valu…
Lower bounds for adiabatic quantum algorithms by quantum speed limits
Jyong-Hao Chen
We introduce a simple framework for estimating lower bounds on the runtime of a broad class of adiabatic quantum algorithms. The central formula consists of calculating the varianc…
Bounds on quantum adiabaticity in driven many-body systems from generalized orthogonality catastrophe and quantum speed limit
Jyong-Hao Chen, Vadim Cheianov
We provide two inequalities for estimating adiabatic fidelity in terms of two other more handily calculated quantities, i.e., generalized orthogonality catastrophe and quantum spee…
